ATTACHMENT Application filedy December To all whom t may concern.'

Be it known that I,`JoHN K. JOHNSON, a citizen of the United States,residing at Washington, in the District of Columbia, have inventedcertain new and useful Improvements in an Attachment for Vindows, ofwhich the following is a specification.

My said invention relates to an Vattachment for windows and it is anobject of the same to provide a means which will prevent windows fromrattling which commonly occurs where the window sash does not .titclosely in its casing.

Referring to the accompanying drawings, which are made a part hereof andon which similar reference characters indicate similar parts,

Figure 1 is a front elevation of a window and its casing with partsbroken away, 2li Figure 2 a vertical section on line 2 2 of Figure 1,

Figure 3 a detail on an enlarged scale,

Figure 4c a transverse section on line 4-4 vof Figure 3, v

'Figure 5, a front view of the lower end of the device as shown inFigure 3, and

Figure 6 a modification.

In the drawings reference character 10 indicates a window -frame whichmay be of any conventional form and in which there is located a lowersash 11 and an upper sash 12. The window frame is broken away at eachside of the window sash to show slots 13 in guide strips 13 for thereception of anti-rattling devices. As shown in Figure 2 these devicesare applied to both the upper and the lower sash,fthe window frame beingcut away for this purpose.

My device is shown on a larger scale in Figures 3 and 1 where the slot13 in a guide strip 13 is shown as adapted to receive a sheet metalbacking and holding plate 14 having at its upper and lower ends,outstanding ears 15 and 2O bent'over the edges of a spring 16. Thespring 16 has at its upper end. a hole to receive a tack, brad or thelike 1T which also passes through a similar opening in the plate 14 andinto the wood of the casing. The lower end of the spring 1n the position'shown and then the springs is free to move between a pair of ears 520yFOR WINDOWS.

bear resiliently against the sash from one side to force it a ainst theguide strip at the other side. gSee Fig. 2.) The sash can be movedfreely by a person opening or closing the window yet the springs preventtoo free a movement of the sashin its slot. As will be seen from Figure2 the springs are preferably placed at the inner side of one sash and atthe outer side of the other so as not only to prevent rattling, but alsoto force the two sashes together at their meeting edges and thus assistin preventing ingress of cold air.

In the form shown in Figure 6 the spring 16 is located in a. plate 14 asabove described, the plate in this instance being secured in adepression formed at the bottom of a side groove in a screen 18 which ismovable on a pair of guide-strips 19 fitting in the grooves, `only onestrip being shown. As will be evident a spring at each side of thescreen will tend to keep the same centered between the guides thusenabling the screen. to be moved up and down readily and withoutsticking in the guides.

Other uses of my device and other forms of the same will suggestthemselves to those skilled in the art and therefore I do not limitmyself otherwise than as indicated in the appended claim..

Having thus fully described my said invention, what I claim as new anddesire to secure by Letters Patent, is:

An attachment for windows comprising a .flat spring', an elongatedbacking member therefor having at 'its upper and lower ends pairs ofoutstanding ears bent reversely upon themselves at their point ofcontact with the backing member to receive therebetween' the respectiveends of the Hat spring, a tack passing through registering holes in thcspring and backing member to support one end of the attachment, and atack passing through t'hc backing member, only to support the other end,the free end of the spring readily passing over the last said tack,substantially as set forth.

In witness whereof, I have hereunto set my hand and seal at Washington,District of Columbia, this 13th day of December, A. D. nineteen hundred.and twenty-two.
